Totally agree with you there. The Polish Lavuu was an interesting design consisting of two poncho halves which are buttoned together. It was purchased so it could be modified easily with it being made from cotton canvas. I was going to install a zip to accommodate a removable 18 inch cotton canvas skirt onto the base to raise its height so it could be used with a BCB camp cot. So weight is really a secondary issue as I already have a number of lightweight tents available.

The Polish Lavuu would also allow me to experiment with the concept of the super Shelter etc.

Other modifications I was going to make would also to include something like a frontier stove or even something similar such as the Titanium Goat WiFi stove to make it a Winter hot tent.
